Patented Sept. 13, 1932 GEORGE A. sAvInLE,-.m.; onrinoon vjnnnneskn Y J ADJUSTABLE wes'rn RECEIVER 1 I My invention relates to waste receivers for catching the shavings and other wastewhen boring the cylinders of internal combustionv The primary object of the invention is the" provision of a waste receiverwhich may be inserted from the top of the cylinder and seated beneath the cylinder where it remains in operative position until the job is. com-H pleted, the waste receiver beingthen remov able through the cylinder. A

Another of my objectsis the provision of a waste receiver-which is colla sible to a size where it may be passed throng the cylinder, the receiver being also expansib-le to seat. underneath the cylinder in such a way thatit will catch all of the shavings and other waste when grinding or boring the cylinder. y More specifically, my object is to provide a waste receiver which may be expanded and contracted by means of ribs which act much like those of umbrellas and parasols.

Another of my objects is the provision of a waste receiver incup form having'itsiabutments on the crank shaft beneath the cylinder and having a spring for forcing the receiver into intimate contact with the bottom surface of the cylinder block. V J Another object of my invention is the provision of a special tool for inserting and re+ moving the waste receiver. V

Having in view these objects and others which will be pointed out in the following description, I will now refer to the drawing, in which Figure 1 is a sectional view of my waste receiver seated in position on the crank shaft with the mouth of the receiver in intimate contact with the cylinder block and underneath one of the cylinders.

Figure 2 is a view in perspective of the waste receiver.

Figure 3 is a view in perspective of the tool employed for inserting and removing the waste receiver from the cylinder, a smallportion of the operating mechanism of the waste receiver being also shown.

The waste receiver itself is shown at10. This is cup-shaped and it may be made from rubber, rubber composition, leather, fabric or I Application filed ma a, i932 Seria1 No. 594,371.

any'o'ther similarmaterial which'is collaps-i i I ible..: The receiver 10 is reinforced by means of a number of ribs 11 whichare preferably a made of-a flat and slightly resilient material. I These ribs extend lengthwise .of'the receiver and they are turned inwardly into radial Iposition' to. cover the bottom of the"receiver.--' The receiver is also provided with a central :1v

aperture in its bottom, the receiverbeingre-I inforced at'this point by means of a collar-.12.. jz A hollow spindle 13 extendsthrough the cenv tral aperture, the ribs 11 being turned up be.-

maybe positionedbeneath the walls 18'of' 'the cylinder and that the pressure of the; 'spring 14E will hold the upper edge of the receptacle in intimatecontact with the r tom of thecylinder block. b p

The ribs 11 terminate atithei'r upper endsi -a little below the upper edge 10f" the cup. In

this manner the metallicparts of the cup will notcontact directly with the-cylinder block,

the cup material beinglslightly overlapped to form a gasket for the cylinder. block. The, cup 10 may also be reinforced at its upper extremity by means of any expansiblemember 19 such as a coil spring or rubber band.

The ribs 11 are braced by meansiof braces.

20 which are pivotally secured to the individ'- ualribsll and to a collar21. The c'ollar21 v is sli'dable on the spindle 13. The upper end portionof the spindle 13 is eXternally threaded for the-reception of a nut 22. The slid able'collar 21 has an internal circular which seatsin a grooveof the nut'22.- It Is evid nt that the turning of the nut 22 will cause the collar 21 to move up or down to thus either'expand or contract the mouth of the 'freceptacle. The nut'22' is provided with a wrenchengaging member 23.

For lifting the cup out through the cylin-- ler after its mouth has been contracted, the" spindle 13 is so formed that it maybe en-v I gagedby a hook. As previously described,

the. spindle 18 is hollow. The opposite Walls of the spindle are provided withbayonet slots 2t-which are adaptedto receive a'hook. The

hollowfportion of the spindle" hasfa plunger:

therein'which is spring pressed by means of a coil spring 26 having its upper end bearing against the plunger 25 and its-lower end bearing against van abutment 27 inside the spindle 18. The hook which: engages vthe bayonet slots 24 must therefore be so formed vthat it will press the plunger :25 downwardly to permit its insertion into .the hollow spindle 13. The plunger 25 closes the mouth of the'bore of the spindle 13 to prevent the entrance of waste.

, The tool employediwith the cup is best shown in Figure 3, parts being also shown In Figure 1. The rod 28 passesthroughasle'eve'j 292Which is knurledv at 80. The'rod 28. has a handle 31 of any convenient form and it ispro vid'ed with a' pin 32 passing through the rod '28 and. projecting from opposite sides I thereof; ;The diameter'of the rod 28 isjsubstantia'lly'that of the plunger 25. "Pressure on' the rod 28*will for'ce down the plunger 7 desired touse thetool to eXpandorcontract the mouth ofjthe receiver, the sleeve 29 is pushed down its full-distance on the rod 28' solthatits wrench socket-33 may be forced into engagement withthe nut head 23.- The "tool shown in Flgure 3 n aythus beused either for expanding or conti'a'ctingjthe mouth of the receiver or t may be used to pull the receiver with its contents out through the top of the cylinder.

Having thus described my invention in suchfull, clear, and exact terms that its construction and operation willfbe readily understood byfothers skilled in the art to which pertains, what claim as new and desire to secure by Letters Patent of the United States is tracted and greater than that of the cylinder when expanded. v
